Bugmeat
From A KoL Wiki
Bugmeat is the term for meat that has entered the game through an error, or 'bug', in the game code. Much of KOL's bugmeat appeared on Black Sunday (August 8th, 2004), the day that a major meat creation bug was found and widely exploited. The bugmeat was created by using a meat vortex from one's inventory while having no meat. Instead of failing to work, it tried to set the player's meat count to a negative number which, due to a minor bug in the game's database, caused it to give 18,446,744,073,709,551,615 meat (the largest possible unsigned 64-bit integer). This has since been fixed. Most bugmeat is removed from the economy through the use of meatsinks, most notably the Penguin Mafia storyline not long after Black Sunday.
